Infrastructure Wireless LAN
The SMC2802W also provides wireless workstations with access
to a wired LAN. An integrated wired and wireless LAN is called an
Infrastructure configuration. A Basic Service Set (BSS) consists
of a group of wireless PC users and an access point that is
directly connected to the wired LAN. Each wireless PC in this
BSS can talk to any computer in its wireless group via a radio link,
or access other computers or network resources in the wired LAN
Infrastructure via the access point.
The Infrastructure configuration not only extends the accessibility
of wireless PCs to the wired LAN, but also extends the effective
wireless transmission range for wireless PCs by passing their
signal through one or more access points.
A wireless Infrastructure can be used for access to a central
database, or for connection between mobile workers, as shown in
the following figure.

SETTING THE COMMUNICATION DOMAIN
27
Setting the Communication Domain
Stationary Wireless PCs
The Basic Service Set (BSS) is the communication domain for
each access point. For wireless PCs that do not need to support
roaming, set the Service Set Identifier (SSID) for the wireless
card to the SSID of the access point to which you want to
connect. Check with your network administrator for the SSID.
Roaming Wireless PCs
A wireless Infrastructure can also support roaming for mobile
workers. More than one access point can be configured to create
an Extended Service Set (ESS). By placing the access points so
that a continuous coverage area is created, wireless users within
this ESS can roam freely. All wireless adapters and access points
within a specific ESS must be configured with the same SSID and
to the same radio channel.

• Make sure the correct software driver is installed for your
operating system. If necessary, try reinstalling the driver.
• Make sure the computer and other network devices are
receiving power.
• The access point you want to attach to may be defective. Try
using another access point.
• If you cannot access a Windows service on the network,
check that you have enabled and configured the service
correctly. If you cannot connect to a particular server, be sure
that you have access rights and a valid ID and password.
• If you cannot access the Internet, be sure you have configured
your system for TCP/IP.
If your wireless station cannot communicate with a computer in
the Ethernet LAN when configured for Infrastructure mode, check
the following:
• Make sure the access point that the station is associated with
is powered on.
• If you still cannot connect, change the access point and all the
stations within the BSS to another radio channel.
• Make sure the SSID is the same as that used by the BSS
configured on the access point, or the same as that used by
the access points in the extended service set (ESS).
